About Sunovion compounds

The four active clinical stage ―ulotaront (SEP-363856), the non-racemic ratio of the enantiomers of Amisulpride (SEP-4199), SEP-378614 and SEP-380135― included in the collaboration cover early to late stage development. The compounds represent a scientifically unique approach to treating symptoms which are not adequately treated by current treatment options and / or for which existing treatments have an unsatisfactory safety and tolerability profile.

Ulotaront (SEP-363856), phase 3, is an amine-associated receptor 1 (TAAR1) agonist with 5-HT1A agonist activity which is being investigated for the treatment of schizophrenia with additional indications under investigation. Ulotaront has been granted Breakthrough Therapy designation from the United States Food and Drug Administration (FDA) for the treatment of schizophrenia. Ulotaront is the first TAAR1 agonist to enter phase 3 clinical studies in adults and adolescents (13 to 17 years old) with schizophrenia.

Non-racemic Amisulpride (SEP-4199) is in phase 3 clinical development for the treatment of major depressive episodes associated with bipolar I disorder (bipolar depression). Sunovion discovered that the pharmacology of Amisulpride is enantiomer-specific and that increasing the R-Amisulpride / S-Amisulpride ratio increases the potency of 5-HT serotonin.7 receptors versus receptors for dopamine D2. SEP-4199 was designed with an 85:15 ratio of R-amisulpride to S-amisulpride to increase serotonin 5-HT levels7 activity to improve the efficacy of antidepressants and to produce reduced levels of D2 receptor occupancy suitable for the treatment of bipolar depression. In September 2021, Sunovion initiated a global Phase 3 clinical study, which is a randomized, double-blind, placebo-controlled, parallel-group, fixed-dose study for the treatment of bipolar I depression in the United States. Japan will join this global clinical phase. 3 study.
